dmesg

For a few years I've observed an issue with DRI3 loading images (any format)
with mpv -vo opengl where only maybe 10-20% of the top left corner is drawn,
and the rest is black. If it's a playlist then the second and subsequent images
are drawn correctly, after the initial window was already created.

It's present with xf86-video-intel and modesetting, and is fixed with
LIBGL_DRI3_DISABLE=1. 

There are similar issues reported such as "blank, black elements" or "gtk
corruption" but these seem to have been reported fixed on some hardware or just
hard to reproduce, I guess. Since I seem to have some insomnia I've decided to
finally report this. ;)

I'll attach a few relevant things in a moment. Also, sorry if I've
miscategorized this.</pre>
